MAINTENANCE AND SERVICE 

Ordinarily, there are no adjustments or maintenance required.  If you need repairs, send the DVX to us.  Call us for help 
in diagnosing the problem, and to get a return authorization and shipping instructions. 

Please save the original shipping carton and packing materials in case you need to ship it for any reason.  If you are 
unable to save the original shipping materials, you must wrap the DVX in at least 3” of bubble-pak or foam rubber 
before shipping.

IMPORTANT  

The primary thing that can go wrong with the DVX drive is that eventually the lasers will wear out.  The lifetime of the 
lasers varies considerably from drive to drive, so it is difficult to predict the lifetime.  However, since recording discs 
uses 10 times the laser power of playing back, using the DVX to record discs will shorten the laser’s life.   

 

To make your DVX last as long as possible, please do not use it for recording

.  Recording uses approximately 10 

times more laser power as reading, and therefore will shorten the life of the laser. 

 

Trouble Shooting 

DVX Does Not Respond 

Rarely, when testing a disc that is thoroughly unreadable, the system may hang and the DVX no longer responds to 
commands.  Since SATA drives are intended to be “hot swappable”, the operating systems constantly polls the drive to 
see if it is still there.  If the drive does not respond within one second Windows thinks that the drive is disconnected and 
disables it.  This can be remedied by re-booting the system. 

Registry Settings 

The DVX installation sets registry entries for proper operation.  If for some reason you need to set these manually, the 
settings are: 

Windows 7 / Vista / XP / 2000 

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ASPI32]  
”ErrorControl” = dword:00000001 
”Start” = dword:00000001 
”Type” = dword:00000001 
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ASPI32\Parameters]  
“Exclude Miniports” = “” 
 [HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer]  
“NoDriveTypeAutoRun”  = REG_DWORD: 0xB1
